  "summary": "Reviewed this ARM assembly file implementing edwards25519 compressed-point decoding and its local field-arithmetic helpers. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators in the target file.\nReviewed this x86-64 assembly implementation of `p256_montjadd_alt`, which performs P-256 Montgomery-Jacobian point addition using only local arithmetic, register saving/restoring, and stack temporaries. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.",
